“…The limit of detection (LOD) of the sensor was determined using the calculation formula LOD = 3σ/k, where k and σ give the liner curve slope and standard deviation, respectively (Figure 8). [35][36][37] The detection limit of Hg 2 + ions by the sensor was calculated using figure 8, 0.1 ppb (0.1 μg/liter). According to the World Health Organization (WHO-1984), 0.006 mg/L of Hg 2 + ions are present in drinking water.…”

This work synthesized a novel colorimetric ligand based on the compound quinazolinone (Sensor) and investigated it. The sensing activity of the sensor toward different cation was studied. The sensor demonstrated a highly selective colorimetric sensing toward Hg 2 + with a detection limit of 0.1 ppb and visual color change from colorless to Purple in methanol-water solvents (v/v, 10,90). The cation binding character was determined using visual inspection, UV-Vis, and fluorescence analyses. In the computational part, the interaction between the receptor and Hg 2 + ion was investigated using density functional theory (TD-DFT) and quantum theory of atoms in molecules (QTAIM) in the solution phase (in the presence of water as solvent and the CPCM model). Theoretical studies have shown that electronic properties such as energy gap, absorption energy, charge/energy transfer, and optical properties change dramatically in the presence of Hg 2 + cations. Also, the effect of the electric field on the electronic properties of the sensor/Hg 2 + complex improved the Hg 2 + cation adsorption process.

Coumarin‐based Chemosensors for Metal Ions Detection

Coumarins, due to their intense and persistent emission of fluorescence, structural flexibility, and excellent biocompatibility, have become a popular choice in developing new fluorescent chemosensors. Coumarins have long been used for sensing anions, cations, chemically reactive nitrogen, oxygen, sulfur-containing species, and small molecules. They have also been shown to have applicability in imaging, biology, and medical research. Due to the widespread use and excellent biological activity, hundreds of such coumarin motifs have either been isolated from nature or synthesized in a laboratory. This review covers all the developments pertaining to the synthesis and use of coumarin for sensing a variety of metal ions (alkali, alkaline earth, transition, heavy, and noble metal ions). This comprehensive review includes an overview of the coumarin-based chemosensor's pH limit, detection limit, and binding mode. A brief explanation of the stoichiometric ratio between metal and chemosensor moiety and the applicability of each chemosensor is also given.

“…Colorimetric sensors that rely on color changes on bounding with the analytes are believed to be one of the most efcient and suitable techniques for detecting inorganic ions and other chemical species [6,7]. Colorimetric chemosensors-based techniques are one of the interesting tools that can be used for this purpose because of their advantages, such as their ability to produce a desirable onsite"naked-eye" response, a reasonable cost, simplicity, selectivity, a low detection limit, immediate response, and high sensitivity [6][7][8]. Chemosensor molecules that can be used for sensing the presence of metal ions must have the ability to bind to metal ions and produce detectable physicochemical changes easily and promptly.…”

The ligand 3-(-(2-hydroxyphenylimino) methyl)-4H-chromen-4-one (SL) has been synthesized and examined as a chemosensor for some metal ions in aqueous solutions based on colorimetric analysis. Color changes were monitored using UV–visible spectroscopy. Binding stoichiometry and limit of detection (LOD) were estimated using titration experimentation based on UV–visible absorbance and Job’s plot. The synthesized ligand was tested for selectivity in the presence of several cations and was examined for possible utility as a chemosensor in real water samples. The results indicated sensing ability and selectivity for Cu2+, Fe3+, and V5+. Stable complexes were formed between SL and Cu2+, Fe3+, and V5+, and the ligand-to-metal binding stoichiometry was found 2 : 1 in the SL-Cu2+ and SL-Fe3+ complexes, and 1 : 1 in the SL-V5+ complex. The results of LOD and bending constant were (7.03 μM, 1.37 × 104 M−1), (5.16 μM, 2.01 × 104 M−1), and (5.94 μM, 1.82 × 104 M−1) for Cu2+, Fe3+, and V5+, respectively.
